ANS names 2027 Congressional Fellows
Loumis
Lockhart
The American Nuclear Society is excited to announce that it has officially selected two of its members to serve as the 2027 Glenn T. Seaborg Congressional Science and Engineering Fellows. Madeline Lockhart and Aristidis Loumis will provide key support to one of the Society’s four strategic pillars of action: informing policymakers to enable better decisions and stronger policies. They will achieve this by serving a one-year term on Capitol Hill either in a congressional member’s personal office or with a congressional committee, starting next January.
Some context: ANS Congressional Fellows are among the nearly 30 scientists and engineers who participate annually in the American Association for the Advancement of Science (AAAS) Congressional Science and Engineering Fellowship Program. More than 2,000 fellows have served through the overarching program since its inception in 1973. ANS initiated its program in 2000, and in 2023, expanded it to host two fellows per year.
